A PPS system (short for production planning and control system ) is a computer program or a system made up of computer programs that supports the user in production planning and control and takes on the associated data management .
The aim of the PPS systems is the realization of short lead times , adherence to deadlines, optimal inventory levels and the economic use of operating resources . ERP systems also include the planning of human and financial resources and can integrate PPS systems.
In the German-speaking area, August-Wilhelm Scheer was one of the first professors who systematically dealt with the use of EDP systems to solve production-related problems. a. developed the Y-CIM model . This model forms the theoretical background for the integration of commercial and technical functions and processes with the help of IT systems (see the literature on A.-W. Scheer). Until the 1970s , mainly paper-based systems were common for production planning and control ( ORMIG method). One of the first suppliers of PPS systems was the IBM company with the COPICS system , which later withdrew from this business.
PPS systems are now offered by many software manufacturers as standard solutions that can be configured by the company, i.e. adapted to their situation. The development mostly takes place in the form of modules . However, many companies, especially large ones, also use individual solutions specially developed for them. Due to globalization, one can often find a mix of PPS standard solutions and individual solutions in global corporations. As a result, the interface management between the various PPS systems and functions in particular is often extensive and complicated.
For many manufacturers, the PPS systems are an integral part of the more comprehensive ERP systems . These also offer u. a. also functions for planning human and financial resources. In addition, there are functions that extend into the procurement processes and structures as well as into the sales processes and structures.
Due to the increasing differentiation in the various branches of industry, some providers of PPS systems, including SAP , have switched to offering special branch solutions in which branch-specific modules are preset. In some branches of industry, such as the automotive industry with a high level of product complexity, a global manufacturing network and a BTO strategy, there may be specific PPS processes (production program creation, option / property prognosis, cumulative figures system) that cannot be mapped by a standard system are.
PPS systems are not intended for direct control of production and production facilities. For the operational control of the production itself there is usually a production control station with a Manufacturing Executive System ( MES ) that controls the production units and systems on site. The production control center or the MES receives the production orders (target data) from the PPS system - via an interface. The production results achieved (actual data) are recorded by PDA and reported back to the PPS system, which takes them into account in the next planning run. In this way, a corresponding control loop for production control can be set up.
There are between 100 and 200 providers on the market, depending on where you stand and how you count. Most providers have specialized in a certain target group .
Focus on large corporations
- Infor ERP LN (formerly Baan )
- Oracle ; formerly PeopleSoft
- Microsoft Dynamics AX (formerly Axapta)
Focus on small and medium businesses
- Abas Business Software
- inforCOM (formerly VPPS)
- Microsoft Dynamics NAV (formerly Navision)
- Sage Group
- eEvolution (formerly Apertum)
Focus on industry-specific requirements
Requirements for PPS systems differ considerably from industry to industry, for example in purchasing strategy (delivery times, bottleneck consideration, missing parts), warehousing (capital commitment, discontinuation tracking) and production type . These systems can also be individually adapted, but the effort is usually less than with standard systems. Some providers equip standard systems with industry-specific modules so that a PPS system can be used for several industries with specific modules in each case.
